Another unseasonably cool day, but a warm spike for Wednesday.

This Afternoon: Becoming Partly Sunny

Highs: Around 60 | Wind: NE 10

Tonight: Mostly Clear

Lows: Mid 40s | Wind: Light and Variable

Wednesday: Mix of Sunshine and Clouds, Warmer

Highs: Mid to Upper 70s | Wind: SSW 10

The clouds are hanging tough this morning mainly along and East of the Blue Ridge, while skies have been clear all morning to the West.  There is an area of low pressure off the Atlantic Coast. It's close enough for the clouds, but far enough that we will stay dry. As it moves to the Northeast this afternoon, we should get some clearing, though clouds may stay pesky, especially along the DelMarVa.  Those clouds sure made a difference in temperatures this morning. Clear skies at night mean cool temps. Look at the difference in low temperatures this morning. 

Morning Lows

It was "clear" who had the clouds(40s) and who didn't (30s).   Even with some clearing expected this afternoon, temperatures are going to be below the average.  The northeasterly flow helps to pull in the cooler air.  Highs will likely get just past the 60 degree mark.  Our average high is 69.  This isn't' too bad of a temperature departure compared with temperatures in the plains.  Look at how much colder it is than average in the lower 48.

Temperature Departure from Average

Tomorrow, winds become southerly and that will help us warm well into the 70s.  In addition, it will draw in moisture from the Gulf and as a cold front approaches, it should trigger some showers and an isolated thunderstorm by Wednesday evening.
